Filing a DBA in Starr County means a trip to the county clerk

Open a taco stand, a welding shop, or a roadside fruit stand under a business name that isn't your legal name, and Texas wants that 'doing business as' name on the public record. For an unincorporated business in Starr County, that record lives with the County Clerk at 401 N. Britton Avenue, Room 201, in Rio Grande City. You file an Assumed Name Certificate, and there's a Certificate of Withdrawal From Business for when you close up or change the name.

An LLC or corporation handles its assumed names differently, through the Secretary of State, so the county filing is really the sole-proprietor and partnership path. A DBA only registers the name. It isn't a sales-tax permit, isn't a city license, and gives you no trademark protection.

And if your shop sits inside city limits — Rio Grande City, Roma, Escobares, or La Grulla — the county DBA doesn't replace whatever permits that city wants before you open the doors. The county records the name; the city handles the storefront.
